How to get “Data” field from xhr.responseText?

Question

I have XMLHttpRequest() function given below

var searchFriendRequests = function (userid) {
    var xhr = new XMLHttpRequest();
    xhr.open(\'G         


        

Answer 1

When you make your ajax request you can provide dataType option:

dataType: 'json'

For such request when you receive response:

If json is specified, the response is parsed using jQuery.parseJSON before being passed, as an object, to the success handler. The parsed JSON object is made available through the responseJSON property of the jqXHR object.

you can access your data like:

var data =  xhr.responseJSON

Full example:

  $ajax.({
    dataType: 'json',
    success: function( xhr ) {
      var yourData =  xhr.responseJSON;
      console.log( yourData );
    },
  });

Answer 2

use JSON.parse(), like:

var data=xhr.responseText;
var jsonResponse = JSON.parse(data);
console.log(jsonResponse["Data"]);

Answer 3

For sometime now you can use:

xhr.responseJSON

without any parsing needed. hope it helps

Answer 4

should parse the response to json object first,then get the data field from the response

var responseText = JSON.parse(xhr.responseText),
     data = responseText.Data;

Answer 5

You first need to parse responseText in JSON, for this you should use JSON.parse(). Then you can access it using key.

var json = JSON.parse(xhr.responseText);
var yourData = json.Data; // or json["Data"]

Answer 6

To simply get the email, or any other field, from the Data object, use the following:

data.Data[0].email
